I'll agree with Sarge here. It is very hard to check suspension when its on the ground, and if you are by yourself. Truck sitting motionless with the weight on the parts, its hard to find a loose suspension parts. You can also jack the frame up in the front to where the tires about 2 inches off the ground, get you about a 4 ft 2x4 and put it under the tires and use the 2x4 as a pry bar and lift the tire and have someone watching your bushings for excessive movement.
